![]() This article presents a comparative study between Proportional-Integral-Derivative (PID), a modified PID structure called I-PD, Fuzzy Logic Controller (FLC) and Fuzzy PID (F-PID) controllers based on time domain characteristics. Simulation results illustrate the practicability of this technique. In this the outputs of the fuzzy logic controller are used as dynamic parameters of PID. It is a technique that auto tunes the PID parameters according to the response of plant. A more adaptive controller using fuzzy logic is built in this study to realize a better control compared with the current PID controller. Considering the non-linear characteristics of the DC motor and its mechanical variations due to operating conditions, the traditional controllers alone are not enough to give precise control. ![]() In this paper, an overview of intelligent control technique for the speed control of a direct current (DC) motor has been discussed.
